Abstract:
The seismic response of a 290 m high arch dam, located in a
high seismicity zone in China, is studied in this paper. The goal is
to evaluate the influence of the reservoir water level on the dam’s
seismic behaviour.
The numerical simulations are carried out using the 3DFE program
DamDySSA3.0, developed in LNEC for linear dynamic analysis of
dams, including a module for seismic analysis under applied base
accelerations. The problem is solved by a Finite Element coupled
formulation in displacements and pressures. The seismic response is
computed in time domain for the dam-reservoir-foundation system
using the Newmark method.
The seismic study is performed for
